FIELD OF THE INVENTION

The present invention relates to the movement of entertainment elements.

BACKGROUND OF THE INVENTION

A wide variety of devices are used for entertainment purposes. Forexample, electronic displays are now extremely common and are utilizedin a variety of environments. Such displays were initially usedprimarily in television sets and to with computers. Initially, thesedisplays were primarily CRT type displays which were large and bulky.

In recent years, other display technologies have been developed. Plasma,LCD, LED and other types of displays are now commercially producible inlarge display sizes. At the same time, however, these displays aregenerally thin, thus taking up much less space than CRT type displaysoffering the same display area.

As such, these displays are now utilized for a variety of purposes. Forexample, large displays are used at stadiums to present replays ofsporting events. These types of displays are also sometimes mounted towalls in stores to present advertising information.

In order to attract attention to advertising, graphic information may bepresented on the displays. This information may comprise excitingpatterns, such as in bright colors, flashing effects and the like, todraw attention to the display. Still, these displays may be overlookedand advertisers and other users of these displays continue to seek newways to use these displays and increase their viewership.

Other types of entertainment devices may be used in other settings. Forexample, in a theatrical production, large props may be located on astage. The props may be moved into various positions to create differentscenes and various actions. The props are often moved manually, such aswith ropes and pulleys, limiting the situations where they may be usedor their effectiveness.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, numerous specific details are set forth inorder to provide a more thorough description of the present invention.It will be apparent, however, to one skilled in the art, that thepresent invention may be practiced without these specific details. Inother instances, well-known features have not been described in detailso as not to obscure the invention.

In general, the invention comprises one or more robotically-controlledobjects and objects which are moved by one or more robots, such aselectronic displays, projectors, projector screens, cameras, musicalinstruments, a staircase, or other elements. One embodiment of theinvention is a robotically controlled electronic display and methods ofusing robotically controlled electronic displays, such as methods ofmoving one or more electronic displays of a group of displays. Anotherembodiment is a robotically controlled video projector and methods ofusing robotically controlled projectors to display images.

Other aspects of theinvention comprise methods and systems for controlling such roboticallycontrolled devices, such as to synchronize movement of a video displayor camera to information being captured or displayed; or the projectionof images from a projector to a projector screen.

FIG. 1 illustrates a robotically controlled electronic display 20 inaccordance with an embodiment of the invention. As illustrated, therobotically controlled electronic display 20 comprises at least oneelectronic display 22 and a robotic or moveable display mount 24. In apreferred embodiment, the electronic display 22 is a thin-panel typedisplay, such as an LCD, LED, plasma or similar display (whether nowknown or later developed). In one embodiment, the electronic display 22has a front or viewing side 25 and an opposing rear side 26. Theelectronic display 22 has a peripheral edge 28.

In one embodiment, the electronic display 22 is generally rectangular inshape, but the display 22 may have a variety of shapes. The electronicdisplay 22 may have a display area at the front side 25, which displayarea is enclosed by a bezel, frame or the like. The display areacomprises the portion of the electronic display 22 which is capable ofdisplaying information.

In a preferred embodiment, the electronic display 22 is relativelylarge, such as for viewing by person situation remotely there from. Theelectronic display 22 may be 20 inches in diagonal size (of displayarea), more preferably at least 36 inches in diagonal size, and evenmore preferably a least 50-60 inches or more in diagonal size. Theelectronic display 22 might comprise a single electronic video displayor more than one display (such as two or more displays which are closelylocated or joined together). The electronic display 22 may be of varioustypes such as CRT, LED, LCD, plasma, etc. and may include touch-screenfeatures, such an overlying touch-sensitive screen.

The electronic display 22 is supported by the robotic mount 24. In apreferred embodiment, the robotic display mount 24 is moveable, thuspermitting the position of the electronic display 22 to be changed. Asdetailed below, in a preferred embodiment, the position of theelectronic display 22 can be changed freely anywhere inthree-dimensional space (not merely one or two dimensions, but in fullthree dimensional space).

In a preferred embodiment, the robotic mount 24 is referred to as“robotic” because it is a device which can change positions withoutdirect manual input. In particular, the robotic mount is preferablycapable of multiple movements without manual intervention (i.e. movebetween various positions based upon a sequence of instructions withouteach movement being prompted by individual user input). Preferably, therobotic mount comprises a robot or robotic arm which is moveable in atleast three (3), and preferably six (6) degrees of freedom, whereby thearm can thus change the position of the display in at least two (2), andpreferably three (3), dimensions.

FIG. 1 illustrated one embodiment of a robotic mount 24. In oneembodiment, the robotic mount 24 comprises a base and a display support.The base is configured to connect or support the display mount andassociated display to a support, and the display support is preferablymoveable relative to the base, thus permitting an associated display tobe moveable relative to the base and the associated support.

Referring to FIG. 1, the base 30 may have a variety of configurations,including various shapes and sizes. In general, the base 30 isconfigured to be mounted to or supported by (by connection or merelyresting or setting upon) a support surface, such as a wall, floor orother support, such as a portion of another object. The base 30 may havea generally planar bottom or lower surface for engaging a generallyplanar support surface, or may have other configurations for engagingsupport surfaces of other shapes. In one embodiment, the base 30 mayinclude one or more apertures for accepting fasteners which are placedinto engagement with the support surface, for securing the base 30 in afixed position by temporarily or permanently connecting the base 30 tothat surface.

In a preferred embodiment, a moveable support is positioned between thebase 30 and the electronic display 22. This support is preferablymoveable in at least three (3), and preferably six (6) degrees offreedom, and is thus moveable in two (2), and more preferably three (3),dimensions or dimensional space. By two or three-dimensions it ispreferably meant the standard Cartesian two or three-dimensional space,such that the support is capable of moving the display about, orrelative to, at least two of an “x”, a “y” and a “z” axis. In apreferred embodiment, movement is permitted in all three dimensions. Asdisclosed below, the robotic mount 24 may permits redundant movement inone or more directions. For example, the robotic mount 24 may includetwo or more elements which permit it to be moved in the x, y and/or zdirection, and to rotate about the x, y and/or z axis.

As illustrated, in one embodiment, the robotic arm includes a mainsupport 32. In one embodiment, the main support 32 is mounted forrotation relative to the base 30, i.e. about the y-axis as illustratedin FIG. 1. The main support 32 may be mounted, for example, on a bearingsupported shaft which is connected to the base 30, or by other means.

In one embodiment, a lower arm 34 is rotatably mounted to the mainsupport 32. As illustrated, the main support 32 has a first portionmounted to the base 30 and a second portion to which the lower arm 34 ismounted. In a preferred embodiment, the lower arm 34 is rotatablymounted to the main support 32 about a shaft or other mount. In theconfiguration illustrated, the lower arm 34 is mounted for rotationabout a z-axis (i.e. an axis which is generally perpendicular to theaxis about which the base 30 rotates).

As further illustrated, an upper arm 36 is rotatably mounted to thelower arm 34. In one embodiment, a first or distal portion of the lowerarm 34 is mounted to the main support 32, and the upper arm 36 ismounted to a top or proximal portion of the lower arm 34. In oneembodiment, the upper arm 36 is also mounted for rotation about the zaxis.

In one embodiment, a head 38 is located at a distal portion of the upperarm 36. Preferably, the display 25 is mounted to the mount 24 via thehead 38. In one embodiment, the head 38 is mounted for rotation relativeto the upper arm 36 (and thus the remainder of the mount 24). In oneconfiguration, a first portion 40 of the head 38 is mounted for rotationabout an x axis relative to the upper arm 36 (i.e., about an axis whichis perpendicular to both the y and z axes, and thus about an axis whichis generally perpendicular to the axis about which the main support 32and upper and lower arms 36, 34 rotate).

Further, in the embodiment illustrated, a second portion 42 of the head38 is mounted for rotation relative to the first portion 40 and theupper arm 36, about the z-axis. As illustrated, the display 22 ismounted to the second portion 42 of the head 38.

The various portions of the mount 24 may be connected to one another ina variety of fashions. For example, the various portions may beconnected to one another via a shaft and bearing mount, where the shaftis connected to one component and engages one or more bearings supportedby the other component, such that the shaft may move relative to thebearing(s), thus permitting the components to move relative to oneanother. The portions of the mount 24 might be mounted to one another inother fashions, however, such as by hinged mounting or the like.

Preferably, the mount 24 includes means for moving the one or moreportions thereof, and thus the display 22 connected thereto. Asillustrated, the mount 24 may include one or more motors M for movingthe components thereof. The motors M may be electrical motors. In otherembodiments, hydraulics or other means may be utilized to move one ormore of the components of the mount 24. For example, a hydraulic armmight be utilized to move the upper arm 36 relative to the lower arm 34in an up and down direction.

In one embodiment, the display 22 may be detachably connected to themount 24, such as to permit the display 22 to be changed or serviced.The display 22 might be connected to a supporting frame, for example.That frame might then be connected to the mount 24, such as byconnecting the frame to the head 38 with one or more fasteners.

As indicated, in a preferred embodiment, the mount 24 is configured tomove the display 22 in three-dimensions, or combinations thereof. Theparticular configuration of the mount 24 may vary for accomplishing thistask. For example, while the mount 24 described above is redundant inits capacity to move in certain directions (i.e. the upper and lowerarms 36, 34 are both configured to move about the z axis), the mount 24could be configured in other fashions (such as by having only a singleportion configured to move in each direction). It will also beappreciated that the number of members or elements which the displaymount comprises may vary. For example, the display mount might comprisea base and a head which is mounted to the based, such as via a swivel,permitting the head to be moved in at least two dimensions. Variousconfigurations of members may also be utilized to effect movement invarious directions. For example, aside from swivels or the rotatingconnections of the display mount illustrated in FIG. 1, members may beconfigured to telescope, slide or otherwise move linearly (i.e. movealong an axis rather than about an axis), or be configured to move alongpaths other than curved paths. For example, the mount 24 may beconfigured to move about the “x” axis, such as to permit the display tobe tilted up and down, to move about the “y” axis, such as to permit thedisplay to be swiveled from side to side, and to simply move along the“z” axis, such as to permit the display to be moved in and out (such astowards or away from a wall/viewer).

In the embodiment illustrated, a single display 22 is connected to asingle mount 24. In another embodiment of the invention, referring toFIG. 2, a unitary display 122 may comprise a plurality of individual orindependent displays 22 located in proximity to one another. In oneembodiment, one or more of those individual displays 22 may be mountedto a mount 24, and thus be configured for movement.

Two or more robotic mounts 24 may be used with one another. FIG. 2illustrates one embodiment of a unitary display 122 comprising nine (9)displays 22. All nine displays 22 are preferably mounted to anassociated mount (not shown). In this manner, each of the nine displays22 may be moved by their associated mount.

FIG. 2 illustrates the displays 22 in an orientation where they arelocated adjacent to one another in a matrix, and in a common plane. Inthe configuration illustrated, there is a central display surrounded bytop, bottom, side and corner displays.

The displays 22 may be moved, however, to other locations and thus otherorientations or positions relative to one another. For example, FIG. 3illustrates the displays 22 in a flower configuration where the top,bottom and side displays are tilted forward relative to the plane whichcontains the central display. The corner displays are rotated and thensimilarly tilted inwardly. In this configuration, the displays arepositioned like the slightly closed pedals of a rose or other flower.

FIG. 4 illustrates the displays 22 again arranged in a matrix and in asingle plane. However, in this configuration, the displays 22 have allbeen rotated 90 degrees, so that the unitary display 122 is taller thanwider.

In one embodiment, each display 22 of the unitary display 122 has anassociated robotic mount. In this manner, each display 22 may be movedindependently of the other. In another embodiment, multiple displays maybe coupled to or otherwise associated with a single mount (such thatgroups of displays are moveable together). In yet another embodiment,one or more of the displays 22 may be fixed and others may be connectedto a mount 24 for movement.

In one embodiment, means may be provided for controlling a single mount(such as illustrated in FIG. 1) or one or more or all of a plurality ofmounts associated with a unitary display (such as illustrated in FIG.2). In one embodiment, one or more mounts may be controlled by acontroller. The controller might comprise, for example, anelectronically or mechanically operated controller.

In a preferred embodiment, the controller may comprise or include acomputing device. Various instructions may be provided from thecontroller to the one or more robots/robotic mounts, causing therobots/robotic mounts to move. For example, a user might provide aninput to the controller, which input is a request to move a particulardisplay from a first to a second position. The controller may generateone more signals or instructions which are transmitted to the requiredmount for causing the mount to so move the display. The signal mightcomprise opening of a switch which allows electricity to flow to one ormore motors for a predetermined period time which is necessary for themotor to effect the desired movement. In another embodiment, the signalmight comprise an instruction which is received by sub-controller of themount, which sub-controller then causes the mount to move as desired.

In one embodiment, the controller may be configured to cause a singlemount or multiple mounts to move in various patterns or other desireddirections. For example, the controller might be programmed to cause thedisplays to move in a particular pattern. Referring to FIGS. 2-4, forexample, the controller may be configured to move the displays from theposition illustrated in FIG. 2 to that illustrated in FIG. 3 or 4, orvice versa. The controller may be custom-programmed or might beconfigured to execute pre-set sequences of movement. For example, thedisplays may be configured to move at certain times, into certainpositions or in certain patterns, to move with music or the like (suchmusic might be presented via speakers associated with the display or viaa separate sound system or the like).

In one embodiment, the controller may include a processing unit capableof executing machine readable code or software. As indicated, thatsoftware may comprise a set of instructions which, when executed, causethe controller to move one or more displays in a predetermined motion orpattern, randomly or otherwise. The software might also or insteadsimply comprise a set of instructions which permits a user to providemanual input to cause a display or displays to move, either in directresponse thereto or to generate a programmed movement (which may beimplemented immediately or be stored for implementation at a latertime).

The controller might communicate with the robotic mount via wired orwireless communications. For example, the controller might comprise adesk-top computer running a control program. The desk-top computer mighttransmit signals via a RS-232 communication link including a wiredpathway to the motor or controller of the robotic mount. Alternatively,the desk-top computer and display mount controller might both includewireless transceivers. In this manner, the controller and roboticmount(s) may be located remotely from one another. The same computermight output images or a video feed to the one or more displays.

In one embodiment, video information may be transmitted to the displayor displays either independently of control instructions or dependentlytherewith. For example, the controller may be configured to bothgenerate display information and/or transmit display information to thedisplays, and control the mounts. The controller might be configured tomove the mounts/displays based upon the information which is displayedby the one or more displays. In one embodiment, the one or more displaysmay be moved synchronously with information displayed by the displays.For example, the displays might be moved synchronously with imagesdisplayed by the displays or with music or other accompanyinginformation.

The invention has numerous advantages. One aspect of the invention is amoveable display. The display may preferably be moved inthree-dimensions (i.e. about three axes which are all perpendicular toone another). In one embodiment, the display is mounted to a displaymount having a display support which is moveable in three dimensions.Preferably, means are provided for automatically or remotely moving thedisplay. As indicated, this may comprise changing the position of one ormore portions of the robotic mount.

One aspect of the invention is a method of remotely or automaticallychanging the position of a display. For example, a display may bemounted to a wall or ceiling in a public area and the position of thatdisplay may be changed at various times in an automatic fashion (asopposed to manual manner, where the position is changed by a personphysically moving the display or its associated mount). This has theadvantage that the position of a display may be moved for variouspurposes, such as for entertainment, for optimizing viewing angle, fordirecting information to viewers in certain locations or areas, or forother reasons. The display might also be mounted to a wall of a home andbe controlled by a user to change the viewing position of the display.

Another embodiment of the invention is a robotically controlledprojector 120. FIG. 5 illustrates one embodiment of a roboticallycontrolled projector 120. Preferably, the robotically controlledprojector 120 comprises at least one projector 122 and at least onerobotic mount 124. The projector 122 may be of a variety of types nowknown or later developed. Preferably, the projector 120 is configured toproject one or more images or a sequence of images (video) onto one ormore surfaces. For example, the projector 120 might comprise a digitallight processing (“DLP”) projector, a CRT, LCD, or other type ofprojector. In one embodiment, the robotically controlled projector 120includes a single projector. However, as illustrated, it might include anumber of projectors 122 a, 122 b, etc.

The robotic mount 124 preferably comprises a robot or robotic armsimilar to that described above and will thus not be described hereinagain in detail. In particular, the robotic mount 124 is configured tomove the at least one projector 122 in three (3), and preferably six (6)degrees of freedom, and thus in at least two (2), and preferably three(3) dimensions/dimensional space. As also indicated above, therobotically controlled projector 120 may also include a controller. Thecontroller may be configured to cause the projector 122 to displayimages or video at certain times, and may be configured to cause therobotic mount 124 to move the projector 122, such as in certain paths.

The projector 122 is preferably mounted to the robotic mount 124. Themount 124 may be used to move the projector 122, thus causing theprojector 122 to display images or video at various locations. Forexample, a robotically controlled projector 120 might be located in alobby and be used to display various information or images upon a screenor another projection surface such as a wall, a floor or the like. Therobotically controlled projector 120 might be used in a theater toproject background images or the like.

It will be appreciated that, like the robotically controlled displaydescribed above, more than one robotically controlled projector 120might be used in tandem. For example, two robotically controlledprojectors 120 might each have a single projector 122. The tworobotically controlled projectors 120 may be configured to move invarious patterns together or independent of one another, such as to showjoint images, synchronous images or the like.

Of course, various other of the features of the robotically controlleddisplay 20 described above may be applied to the robotically controlledprojector 120.

In one embodiment, the content of video or other information which isprojected by the robotically controlled projector 120 may be registeredto multiple surfaces upon which the information is projected. Forexample, information may be projected by the robotically controlledprojector 120 onto one wall of a theatre, then the ceiling and then anopposing wall, such as when an image of a character is projected so thatit appears the character is moving up one wall, across the ceiling anddown the other wall of the theatre.

In another embodiment, one or more surfaces upon which the video orother information is registered are robotically controlled projectionscreens. FIG. 8 displays an embodiment of a robotically controlledprojector screen. Such robotically controlled projector screens cancause the projector screen to be moved by a similar type robotic mount.This embodiment will be discussed in detail, below.

Of course, these principles may be applied to various settings. Forexample, the projection surface(s) could vary. While the surfaces mightbe associated with the exterior of the building, they could be theexterior of a building or other structure, the ground, or otherarchitectural elements, whether natural or man-made.

Yet another embodiment of the invention comprises a roboticallycontrolled staircase 220. FIGS. 6 and 7 illustrate a roboticallycontrolled staircase 220. The robotically controlled staircase 220comprises a staircase 222 and a robot or robotic mount 224 which isconfigured to move the staircase 222.

The staircase 222 may have various configurations. In one embodiment,the staircase 222 comprises a supporting body or structure 226. Thestaircase 222 preferably includes a plurality of steps 228. Each step228 may comprise a riser 230 and a landing 232. Each riser 230preferably extends generally vertically upward. The number of steps 228,and thus the number of risers 230, may vary. Preferably, there is atleast one step 228. More preferably, however, there are a plurality ofsteps 228. The depth of each landing 232 and the height of each riser230 may be configured to conform to local building or other codes.

Preferably, the staircase 222 has a first or bottom end 234 and a secondor top end 236. The top end 236 is preferably higher than the bottom end234. The total change in elevation is dependent upon the number of steps228 and the height of the risers 230. The staircase 222 may be straightor it might be spiral, have one or more bends or the like.

In one embodiment, the staircase 222 may be configured to mate with oneor more other elements or structures. For example, the staircase 222 maybe configured to dock or mate to a supporting platform (not shown). Tothis end, the top end 236 and bottom end 234 of the staircase 222 mayend or terminate in a landing 232. This allows the top and bottom ends236,234 to rest upon a supporting surface or platform at generally thesame elevation thereof. In one embodiment, the landing at the top end236 and/or bottom end 234 of the staircase 222 may be larger than thestep landings 232. For example, each of the top and bottom end landingsmay be sufficiently large to permit one more persons to easily standthereon (whereas the step landings are primarily configured to permit auser to simply step thereon as they climb the staircase).

In one embodiment, the staircase 222 may include other features. Forexample, the staircase 222 may include one or more handrails (notshown). The staircase 222 has a width between opposing sides. This widthmay vary, such as being 36 or 48 inches, for example. A handrail may belocated at each side of the staircase to prevent a user from falling offof the staircase and to provide support to users. Likewise, the landing232 at the top end 236 and bottom end 234 of the staircase 222 mayinclude an enclosure. Such an enclosure may be selectively opened andclosed to permit ingress to and egress from the staircase, but preventsuch during movement of the staircase. Such an enclosure might comprisea rail, a chain, or the like. For example, a swinging gate may belocated at both the top and bottom ends 236,234 of the staircase 222 tocontrol ingress to and egress from the staircase 222.

In one embodiment, the body 226 of the staircase 222 might comprise asuperstructure which supports the steps 228. For example, the body 226might comprise a metal framework. The steps 228 might be constructedfrom wood and be supported by that framework. In another embodiment, thebody 226 might define the steps 228. For example, the staircase 222might be constructed from metal, such as step elements which are weldedto one another to form a unitary structure.

The mount 224 preferably comprises a robot or robotic arm similar tothat described above and will thus not be described herein again indetail (for example, such may comprise a base and a moveable support, asdetailed above). In particular, the mount 224 is configured to move thestaircase 222 in at least two (2), and preferably three (3) dimensions.As also indicated above, the robotically controlled staircase 220 mayalso include a controller to move the staircase 222 in certain paths.

As best illustrated in FIG. 7, the staircase 222 is preferably mountedto the mount 224. As illustrated, an adaptor 240 may be used to connectthe staircase 222 and the robotic mount 224. The adaptor 240 may havevarious configurations. FIG. 7 illustrates one configuration in whichthe adaptor 240 engages a bottom portion of one or more of the steps228. However, the adaptor 240 could have other configurations, such asdepending upon the configuration of the staircase 222, including thebody 226 or supporting structure thereof.

As illustrated in FIG. 6, the robotic mount 224 is configured to movethe staircase 222 between various positions. For example, the roboticmount 224 may move the staircase 222 into a position in which its bottomend 234 is positioned on the ground. A user may then step onto thestaircase 222 from the ground, such as by stepping onto a lower landing232 thereof.

The robotic mount 224 may then be used to move the staircase 222, andthe user standing thereon, to another location. In the preferredembodiment where the robotic mount 224 can move in three dimensions, thestaircase 222 may be moved to various positions in three-dimensionalspace which vary from an initial or starting position. FIG. 6illustrates one simplistic embodiment where the staircase 222 is movedin two dimensions: upwardly and forwardly. In this example, thestaircase 222 may be moved upwardly and forwardly, such as to dock witha raised platform 262. A user might then disembark from the staircase222 onto the platform 262.

It will be appreciated that a user may climb up and down the steps 228of the staircase 222 both while the staircase 222 is stationary and/orwhile it is moving. For example, a user might board the staircase 222 atthe bottom end 234 while it is stationary. As the staircase begins tomove to a destination, the user might climb the steps 228 to the top end236 of the staircase 222 to disembark the staircase 222 at thedestination.

The robotically controlled staircase 220 might be used in variousmanners. For example, it might be used in a theater. In such anenvironment a singer might be transported from stage level to a platformwell above stage, or from one location to another over a barrier such asa moat. The robotically controlled staircase 220 might also be used asan amusement ride. In such an embodiment, patrons might board thestaircase 220 as a ride and be transported from one location to another.In one preferred embodiment, a haunted house ride might include one ormore platforms in various locations. The platforms might lead to doorsor other points of entry. Patrons might board the staircase and betransported to one or more of those platforms where they disembark totravel into other portions of the haunted house. In one embodiment, thestaircase might move between various locations before stopping, thusproviding substantial anticipation to the riders as to their finaldestination. It is also possible for there to be more than onerobotically controlled staircase 220. The various staircases 220 mightmove independently between various locations. They might also move sothat they join together at certain times (forming longer staircases toconnect to various locations, for example) or independently at othertimes). As yet another example, a first robotically controlled staircase220 might be used to move patrons from ground level to one or moreplatforms at a first level (above ground) and then a second roboticallycontrolled staircase 220 might be used to move patrons from the firstlevel to an even higher second level (or higher).

As indicated, one or more controllers may be used to control therobotically controlled staircase 220, such as to cause it to movebetween various locations. The patterns of movement may change overtime. For example, in a haunted house ride, the robotically controlledstaircase 220 might be configured to move a first set of riders fromground level to a first platform. However, the robotically controlledstaircase 220 might be configured to move a second set of riders fromthat same ground level to a second, different platform.

Of course, the robotically controlled staircase 220 might be configuredto move between various locations other than ground level and variousplatforms. The robotically controlled staircase 220 may include severalof the other features detailed herein. For example, the roboticallycontrolled staircase 220 may be controlled by one or more controllers,such as to move in certain patterns or paths, including synchronouslywith other elements. For example, the robotically controlled staircase220 may be moved synchronously with music which is being played or withimages that are being displayed.

As indicated above, another embodiment associated with moveableentertainment elements is that of a robotically controlled projectorscreen. Referring once again to FIG. 8, an embodiment of a roboticallycontrolled projector screen 320 is shown. The robotically controlledprojector screen 320 comprises a projector screen 322 and a roboticmount 324 which is configured to move the projector screen 322. Theprojector screen 322 is attached to the robotic mount 324 through arobotic arm 326 similar to that described above and will thus not bedescribed herein again in detail (for example, such may comprise a baseand a moveable support, as detailed above). In particular, the roboticmount 324 is configured to move the projector screen 322 in at least twoand preferably three dimensions. As also indicated above in relation tothe electronic display and robotically controlled projector, therobotically controlled projector screen 320 may also include acontroller (not shown) to move the projector screen 322 in certain pathsor positions in accordance with a pre-defined software program.

As best illustrated in FIG. 8, the projector screen 322 is preferablymounted to the robotic mount 324. An adaptor 340 may be used between therobotic arm 326 and the projector screen 322 to connect the projectorscreen to the robotic mount 324. The adaptor 340 may comprise variousconfigurations and may depend on the support structure 342 used with theprojector screen 322.

The support structure 342 can be fashioned in any manner sufficient tosupport the screen surface 344 of the projector screen 322 so that thescreen surface is enabled to provide a surface area sufficient toregister the video, graphic or other information emanating from aprojector. Such support structures might comprise a bracketed woodenframework, a metal frame, or it could be formed using a network of PVCpipes or the like. In the embodiment shown in FIG. 8, the adaptor 340 isfirmly attached to a central support bar 346. The attachment point ispreferably engaged at the center of the central support bar 346 toprovide optimum stability to the projector screen 322, and is attachedthrough any attachment means known in the art.

The screen surface 344 is arranged to entirely cover the front portion348 of the projector screen 322 and set taut to prevent folds in thematerial and to best provide a smooth, consistent surface for viewingwithout any imperfections transferred to the image through such folds.Material used for the screen surface would possess properties bestsuited for reflecting light with minimal alteration. Such materialsmight comprise white blackout cloth, any material painted over with areflective, white paint, white vinyl and white spandex. The lattermaterial—spandex—possesses the property of elasticity, and is used in apreferred embodiment, which will be further discussed, below.

Depending on the material, the screen surface 344 may be attached to thefront portion 348 of the support structure 342 through any attachmentmeans known in the art, such as adhesives, nails, staples, Velcro, tacksor the like. Screen surfaces that have sufficient elasticity might bestretched to the back portion 350 of the support structure to tightlyenvelop and wrap around the support structure, and thereby help toprovide a taut, consistent, and uniform surface.

FIG. 9 provides a closer look at the projector screen 322. In apreferred embodiment, the projector screen 322 uses a screen surface 344made of an elastic material, such as spandex. In its static or expanded(i.e. stretched) form, the screen surface is flat, as is typical of mostprojector screens. This is shown in FIG. 9(a). Through the use ofspandex or other elastic material, the screen surface can be manipulatedinto various shapes and forms. An example of this is depicted in FIG.9(b). In FIG. 9(b), a round object such as the ball 420 is pushed intothe screen surface 344 from the back portion 350 of the projector screen322, thereby pushing the elastic screen surface out in a mannerconsistent with the shape of the ball. As will be described, suchforming or manipulation of the screen surface 344 can provide a uniqueand dynamic viewing experience that can be easily changed from one formto another in a relatively quick manner.

It should be understood that although a ball 420 is shown in FIG. 9(b)to depict modification to the flat screen surface 344 of FIG. 9(a), anyobjects and multiple objects could be used to form any type of“landscape” to the screen surface. For instance, a section of a cylindercould be used to provide a convex shape across the entire screen surface344. Further, a number of triangular and/or cone-shaped objects could bepositioned on the back portion 350 of the screen surface 344 to depict alandscape of hills, mountains or waves. Any number or types of shapesand forms that could be used to vary the surface of the screen surface344. The projected image would preferably be consistent with the given“landscape” to enhance the imagery viewed by the persons viewing theprojector screen 322.

In one embodiment, the robotically controlled projector screen's motionis controlled by the controller of the robotic mount 324 in a mannersimilar to that of the electronic display 22, and the projector 122. Therobotically controlled projector screen 320 may therefore be moved froma first position to a second position through the controller in responseto a signal stemming from the coded instructions stored in a memorystorage unit and read by the processor. The movement to and from variouspositions can serve the purpose of placing the screen surface 322 inoptimum position for viewing by the intended viewers to, for instance,reduce glare or to receive viewers at a location where they are bestenabled to view the screen surface. The movements may also be controlledfor the purpose of providing an entertaining element to the pattern ofmotion. For instance, the screen surface 322 may be programmed to movetowards an audience when the projection displays an object, such as abaseball just hit by a batter, moving towards the audience. If thescreen surface 322 is also moving towards the audience, an enhancedeffect is achieved in showing the ball moving in their direction.

To further provide enhanced effects, as previously described, an elasticmaterial, such as spandex, can be used as the material for the screensurface 344. Referring to FIG. 10, the ball 520 is shown beingpositioned into place. The ball 520 is then pressed into the back of thescreen surface 344 at the same moment that a baseball, projected from aprojector 522, is projected onto the protrusion 524 of the screensurface to accentuate the image of the projected baseball. Theprocessing of movement can be established through the synchronization oftiming between the images projected and the motion of a separate roboticmount used for pressing the ball 520 into the screen surface 344 at itsintended position. Of course, alternatively, the ball could be manuallypressed into the back of the elastic screen by an individual having anawareness of the timing and location for doing so. However, the use of arobotic mount for coordinating these activities automates the process,leaves little room for mistakes and creates a more entertainingarrangement of automated, mechanically moving machines to create theoverall visual impression.

To accomplish synchronization, a time code is generated. The time codeis typically established in the projector as an audio signal on an audiorecording device, but may comprise any type of signal. The code can bebroken down into a specific number based on hour, minute and second foreach frame. For example, for a given frame, a certain display, such asthe baseball being hit by the batter, might initiate at hour 2, minute33, and second 42 associated of the 531^(th) frame of the projectedsequence. This may be defined as 023342000531, or some other readablestring that accurately codes this specific information. If the projectorrenders thirty frames per second, the granularity in coordination withother activities can be very precise. The separate robotic mountcontrolling the ball 520 is provided the same time code and both that ofthe projector and separate robotic mount controlling the ball areinitiated at the same moment. Therefore, when the ball is projected asbeing hit by the batter, the ball 520 is moved into position by theseparate robotic mount so that the projection and screen surface 344coordinate in synchronicity. The coded instructions in the separaterobotic mount instruct the controller to move the ball 520 into therespective position when the applicable time code is read. The codedinstructions might also provide the controller instructions as to theprecise location of placement, rate of placement and when to remove theball 520 from the screen surface 344.

The above described example is but one of many. Nearly any object can bepressed into the back of the screen surface 344 to impress on the screensurface a myriad of different volumetric shapes for accentuating imagesprojected on to the screen surface by a projector. Additionally, thoughthe above embodiment was described in terms of a separate robotic mountmoving the ball 520 into position behind the screen surface 344, it isconceivable that this could be performed by an individual, by therobotic mount absent timed computer code instructions to coordinate withthe projector, or by any other means.

Using a time code synchronized and initiated concurrently betweenvarious devices, a number of other entertaining features can be deployedby the robotically controlled projector screen 320 or by multiplerobotically controlled projector screens. FIG. 11 shows a sequence ofsynchronized movements coordinated as between each of two roboticallycontrolled projector screens 620(a) and 620(b) and two roboticallycontrolled projectors 624(a) and 624(b). The movements are coordinatedusing computer coded instructions sent to the controller of therespective devices. The timing of specific motions of each of thedevices is initiated in accordance with pre-defined time codes. Each ofthe computer coded instructions for each of the respective devices isinitiated simultaneously or in a pre-defined sequence. The initial timecode in this example for each of the devices, if their respectiveinstructions were simultaneously initiated, would be 0101010000001,indicating in this example the first second of the first minute of thefirst hour with respect the first frame of the video for each of thedevices, if their respective programs were simultaneously initiated. Allof the devices are therefore pegged to the display presented on at leastone robotically controlled projector screen. It should be noted that thehour/minute/second sequencing is not literal in this example, but ismerely one of many means for apportioning segments of time in relationto a given frame of a video sequence. Upon the occurrence of varioustime codes, instructions are sent to the controller of a respectivedevice to perform a particular motion or set of motions. The initiationof the time code at each of the devices can be manually established bymechanically opening a switch or, preferably, through remote wireless orwired electronic means.

FIG. 11(a) illustrates an embodiment of the invention. Each of tworobotically controlled projectors 624(a) and 624(b) separately display avideo image on each of two robotically controlled projector screens620(a) and 620(b). The image is of a school of fish on screen surface644(a) of projector screen 620(a) and is of a calm ocean environmentshowing a relatively small area of space above the surface on the screensurface 644(b) of projector screen 620(b). Each of the devices operatesat that moment in accordance with instructions respectively assigned toeach device based on a specific time code 628. Such “operation” may bean instruction to remain static or may be no instruction, therebyestablishing a lack of motion in the respective device; or it may be aninstruction sent to the robotic arm to position the respective device,be it all or any of the projector screens 620(a) and 620(b) or therobotic projector 624(a) and 624(b).

As illustrated in FIG. 11(b), the video display shows the fish startingto swim faster with one breaching the water. The robotically controlledprojector 624(a) is sequenced at this moment to move the robotic arm inan upward motion at the same time that the video projection shows morearea of space above the surface of the water with the breaching fishabove the surface. In this manner, it appears that the projector screen620(a) is actually a viewer moving upwards to show the fish breach thesurface of the water; following the fish's path and trajectory. Theocean setting remains the same but a different perspective is provided.Thus, the ocean water surface level between the two projected images isshown to be approximately the same as between projector screen 620(a)and 620(b), but one is now able to see the breaching fish in its properperspective in relation to the ocean setting. Robotically controlledprojector 624(b) moves the robotic arm horizontally away fromrobotically controlled projector 620(a) to put distance between them sothat when the fish re-enters the ocean water, it appears as if the fishhas jumped quite a distance. In timed sequence, the robotic arms ofrobotically controlled projectors 624(a) and 624(b) move the projectors626(a) and 626(b) in proper position and angle to display the videoimagery on the respective projection screens 620(a) and 620(b). Thesynchronized movements initiate at another time code (not shown) and arefurther controlled via subsequent time codes. The position during thesynchronized movements of the robotic projectors 624(a) and 624(b) andprojector screens 622(a) and 622(b) as shown at the given momentindicated in FIG. 11(b) are defined by the instructions associated withtime code 630. At yet another time code 632, FIG. 11(c) shows thebreaching fish splash and submerge into the waters depicted on projectorscreen 622(b), with the other fish shown swimming quickly away fromprojector screen 620(a) on the same screen. Robotically controlledprojector 624(a) moves back down and horizontally towards projectorscreen 620(b), this time displaying an image of a shark moving towardsthe school of fish. The position of the synchronized events shown inFIG. 11(c) corresponding to the described image and movements occur attime code 632.

In the above described embodiment, separately controlled robotic mountscan be used to press objects into the back of the projector screens622(a) and 622(b) to, for instance, emphasize wave motion of the waterand, when the breaching first breaches the water and re-submerges, toemphasize the splash and resulting shock wave. These robotic mountswould similarly operate in synchronicity with the robotically controlledprojectors 624(a) and 624(b) and robotically controlled projectorscreens 620(a) and 620(b) in accordance with the time code sequence andthe coded instructions programmed for implementation upon and theoccurrence of various time codes.

Since the robotically controlled projector screens 620(a) and 620(b) aremoving in relation to the robotically controlled projectors 624(a) and624(b), the aperture of the projector must necessarily be adjusted tomaintain focus of the projected image on the projector screens. This,too, can be controlled through programming in association with the timecode sequence used to coordinate the movements of the various devices orentertainment elements. Thus, in FIG. 11(b), as the projector screen620(b) moves further away from the robotic projector 624(b), either thedistance between the robotic projector and projector screen can bemaintained to eliminate the need to adjust the aperture, else thecontinuous time code sequences can deliver continuing instructions tothe projector indicating the adjustments needed to the aperture (andtherefore the focus) to account for an increase or decrease in therelative distance between the projector screen 620(b) and roboticprojector 624(b). Knowing the relative motions of the projector screenand robotic screen, distances can be determined and adjustments to theaperture can be made, accordingly. They can also be determined through“dry runs” whereby the entertainment elements are made to perform all ofthe respective movements while the proper aperture setting is determinedin accordance with the changes in relative distance between the devices.This may be performed manually at the various positions, and laterentered as program instructions that control these devices and, in thisinstance, namely the robotic projector's aperture setting. Any othermeans known in the art for maintaining focus may be used to maintainfocus between robotic projectors and robotic screens during synchronousmotion where the relative distance varies between the associateddevices.

Other robotically-controlled entertainment elements are contemplated bythe invention. For example, one or more speakers (electro-static, hornor other type) might be associated with a robotic mount, therebyallowing the position of the one or more speakers to be changed orcontrolled in the manner described herein. As other examples, one ormore light generating or emitting elements (such as one or more lasers,spot lights, light racks or the like), microphones, musical instruments(guitars) or associated equipment (amplifiers), etc., might beassociated with a robotic mount. Of course, combinations of suchelements might be associated with one or more robotic mounts. Forexample, an electronic video display and one or more speakers might beassociated with the same robotic mount and thus be moved together inthree-dimensional space. Any of the above elements can be included inthe embodiment shown in FIG. 11 to further enhance the entertainmentexperience. For instance, speakers and lights could be repositioned insynchronicity with the movements of the robotically controlled projectorscreen or in some other pre-programmed manner to provide an audio andexternal lighting experience to coincide with the display. Each of theserobotically controlled entertainment elements can be coded to correspondin synchronicity with the other elements through implementation of thesame time code sequences. For instance, when the fish splashes into thewater in FIG. 11(c), audio elements associated with the aforementionedentertainment elements, including the robotic projectors 624(a) and624(b) and projector screens 620(a) and 620(b), could be made to receiveinstructions at the proper time code to play an audio file that providesa splashing sound through robotically controlled speakers that may alsomove in synchronicity with the other entertainment elements.

Another embodiment of the invention comprises at least one roboticallycontrolled image/video capture device, such as a camera (such as stillor moving picture camera; may be film, digital or other types as is wellknown). Preferably, at least one camera is associated with a roboticallycontrolled mount, such as described in detail above.

As one aspect of the invention, the position of the camera is controlledby the robotic mount. In this manner, the camera captures images, suchas moving picture images, from different positions at different times(rather than where a camera is fixed in position and captures images ofan object that is moving). Of course, the position of the camera may bechanged using the robotic mount, such as to create various effects whichare apparent upon playback of the image(s) or video. In one embodiment,a robotic video display may be used to display the images or video,where the position of the video display is changed based upon theposition of movement of the camera. For example, the video display maybe moved to match the movement of the camera (i.e. the position of thevideo display during playback is synchronized to the position of thecamera during image capture).

The robotically controlled camera can stream or otherwise send images orvideo content to either of the robotically controlled display orrobotically controlled projector for projection to the roboticallycontrolled projector screen. The robotically controlled camera canoperate in synchronicity with the robotically controlled display and/orthe robotically controlled projector and robotically controlledprojector screen. A multitude of coordinated movements can beestablished between all of the respective robots, in conjunction withvideo/image projection, video/image display and streamed video or stillimages from a camera or other image/video capture device to produce amyriad of entertaining displays.

It will be appreciated that the configuration, including size, of arobotic mount may vary, such as depending upon the application. Forexample, a robotic mount which is configured to move a 60 inch LCDdisplay may be much larger than a robotic mount which is configured tomove a spot light.

The invention has other aspects and features. As one aspect of theinvention, the robotic mount may be controlled via data which includesone or more time codes.

In one embodiment, as described above, movement of the robotic mount maybe based upon or tied to what is displayed on a video display (i.e.synchronized). In one embodiment, a data stream may be generated whichincludes both robotic mount control instructions and video data which isutilized by the one or more video displays to cause video to bedisplayed by the one or more displays.

In accordance with the invention, a robotic mount is advantageouslyconfigured to move one or more entertainment elements, preferably inthree-dimensions. The entertainment elements may thus be “animated”,providing a much higher level of entertainment value. For example, themovement of one or more video displays adds entertainment value to theinformation or images displayed by the one or more video displays.Likewise, the movement of one or more video projectors allows thelocation of projected images to change, thus adding excitement to theimages themselves. Similarly, the movement of a staircase may be used toentertain observers or riders of the staircase.

It will be understood that the above described arrangements of apparatusand the method there from are merely illustrative of applications of theprinciples of this invention and many other embodiments andmodifications may be made without departing from the spirit and scope ofthe invention as defined in the claims.
